I live outside Atlanta, GA and winters do not get too cold here. When it drops below 32 degrees I have a 100 watt lightbulb inside my 8 foot by 8 foot by 7 foot tall coop. I will be going out of town on vacation for a week and have concerns about leaving the lightbulb attached to a timer unattended while I am gone. The weather is forecasted to drop to around 21 degrees a couple of the nights and then up to around 34 degrees the remaining nights. Will my Rhode Island Reds be OK for those few days without a lightbulb? There is a slight bit of ventalation (sp?) but no major drafts. Don't worry, I have someone coming by to feed and water them so that is not a concern. Thanks for any info that you may be able to provide. Jon Woodstock,GA P.S. The lightbulb is screwed into one of those clamp lights that hangs from the rafters. It is not into a permenent mounted light fixture, that is why I have a concern.
